[0002]
[Prior art]
In a normal product provided to consumers through a distribution stage from manufacturing, a packaging form having an exterior capable of handling the product as an independent item individually is called “individual packaging”. In the field of absorbent products, general packaging products are intended for women such as sanitary napkins, panty inner bags, and light incontinence pads. In addition, disposable panties have become common for travel.
[0003]
The following items can be cited as functions commonly required for these individually packaged absorbent products. Ie
(1) It is compact and can be carried in a pochette or handbag.
(2) A place and container to be disposed are prepared, and it does not become so large after use.
(3) It is difficult for humans to touch it when carrying it, during use, or after disposal.
(4) It can be kept clean and is hygienic.
[0004]
For example, in the case of a sanitary napkin that is individually packaged, in order to improve convenience when taking it out from the individual package bag, the release tape is connected to the individual package bag and the entire sanitary napkin is opened by simply opening it. What is called a one-way wrap or one-step wrap that can be taken out from a packaging bag very easily has become the main one. At the time of using such individually packaged sanitary napkins, the sanitary napkins are taken out from the individual packaging bags and mounted at predetermined positions on the lower side. Individual wrapping bags are discarded as they are, or used napkins are wrapped in individual wrapping bags, and further wrapped with tissue or the like, and then discarded in a trash container.
[0005]
[Problems to be solved by the invention]
In conventional packaged absorbent products with improved convenience, especially sanitary napkins, individual packaging bags and absorbent products are bonded and held so that they can be peeled off using a release sheet such as silicone-processed paper or specially processed film. Therefore, there is a problem that the cost for individual packaging increases, and garbage such as individual packaging bags and release sheets is always generated.
[0006]
There is a possibility that sanitary napkins of individual packaging type may be discarded as they are after taking out the sanitary napkin, even though the individual packaging bags are originally developed as disposal bags for used napkins. There is a waste of resources. Also, when using the individual packaging bag after removing the sanitary napkin as a disposal bag to wrap the used napkin, it is necessary to put it in a pochette or handbag and carry it until the next replacement. troublesome.
[0007]
On the other hand, the individual packaged absorbent product having the functions (1) to (4) is applied to a diaper for children, an incontinence pad having a large absorption capacity, an urine pad for adults, or a diaper for adults. It is pointed out that it is difficult in terms of profitability commensurate with costs and handling at the time of disposal.
[0008]

【Example】
Examples relating to an absorbent product according to the present invention, a method for producing and handling the same, and an undercoat using the same will be described in detail with reference to FIGS. 1 to 30, but the present invention is limited to these examples. The present invention is not limited to these, and can be further combined, or any changes and modifications included in the concept of the present invention described in the claims, and thus naturally apply to other techniques belonging to the spirit of the present invention. be able to.
[0031]
  The external appearance of the first embodiment is shown in FIG. 1, the longitudinal sectional structure is shown in FIG. 2, and the developed state is shown in FIG. That is, the absorbent product P in this example is,liquidAn impermeable individual packaging sheet 11, an absorbent body 12 that is integrally stacked on the individual packaging sheet 11, and at least one end side of the absorbent body 12 (usually the lower side when used) are accommodated. A trap sheet 14 that forms a flexible trap 13 between the individual packaging sheet 11 and at least one of the other end of the trap sheet 14 and the individual packaging sheet 11. The other end portion of the individual packaging sheet 11 and one end portion of the individual packaging sheet 11 or the trap sheet 14 are detachably joined so that the other end side thereof overlaps the trap sheet 14.
[0032]
The trap part 13 formed by the individual wrapping sheet 11 and the trap sheet 14 accommodates at least one end part of the absorber 12, and is kept in a sealed state so that the trap part 13 itself does not leak according to the use form. And the case where liquid permeation is enabled by using a liquid-impermeable inner bag described later.
[0033]
As a usage pattern in which the trap part 13 needs to be kept in a sealed state, that is, liquid impervious, first, the absorber 12 stored in the trap part 13 is covered with a strong holding sheet such as a top sheet or a back sheet. In other words, the absorbent material such as SAP or pulp is simply wrapped with a thin covering material such as tissue. In this case, since it is necessary to prevent liquid leakage from the absorbent material, the trap portion 13 is made liquid impermeable. The second example is a case where it is used for urine treatment particularly for men. While SAP can hold a large amount of liquid, it has a characteristic that the absorption rate of the liquid is slow. When the absorber 12 containing such a SAP in a high ratio is used, the absorption rate of urine by the SAP is high. However, it is necessary to prevent leakage of urine that cannot be absorbed by the absorber 12 to the outside. In such a case, the liquid-impermeable trap portion 13 can function as a flexible container that temporarily stores urine.
[0034]
As a usage form in which the trap part 13, particularly the trap sheet 14 is made liquid permeable, first, a liquid-impermeable inner bag is used together. The inner bag is accommodated in the trap part 13. In this case, since the trap part 13 only has a function of accommodating the inner bag, the trap sheet 14 can be made porous or mesh-like, or the trap sheet 14 can be made of a hydrophilic nonwoven fabric or the like. it can. The second example is a case where it is used as a urine treatment pad for women, but even in this case, at least one end side (lower end side) of the trap sheet 14 is liquid-impermeable and absorbed by the absorber 12. It is necessary to prevent urine that cannot be cut out from leaking outside.
[0035]
Each of the individual packaging sheet 11 and the trap sheet 14 in the present embodiment is made of a liquid-impermeable flexible PE sheet or a laminated sheet of a PE film and a nonwoven fabric, and the trap sheet 14 is arranged in the longitudinal direction of the individual packaging sheet 11. A trap in which the other end side (upper end side) of the trap sheet 14 is opened by overlapping the one end side and heat-sealing the outer peripheral edge of the individual packaging sheet 11 where the trap sheet 14 overlaps to form a heat seal 16. The part 13 can be formed.
[0036]
When the individual wrapping sheet 11 and the trap sheet 14 are made of the same synthetic resin film material, one long sheet is folded, and both side edges in the width direction of the folded portion of the long sheet are heated and melted. It is possible to form the individual packaging sheet 11 having the trap portion 13 and the trap sheet 14 by wearing.
[0037]
The other end side of the absorbent body 12 in this embodiment is exposed from the opening 17 of the trap portion 13 and extends to the other end side of the individual packaging sheet 11. In the unused individual packaging state shown in FIGS. 1 and 2, the individual packaging sheet 11 is folded back onto the trap sheet 14 together with the individual packaging sheet 11 from the middle in the longitudinal direction and covered with the individual packaging sheet 11. It is in the state. The used absorbent product P can be discarded without soiling the hands by changing the folded state of the folded portion shown in FIG. 2 to the folded state shown in FIGS. 1 and 2 again.
[0038]
By using the liquid-impermeable individual packaging sheet 11, the absorbent 12 has a normal absorbent material mainly composed of an absorbent material such as SAP or wood pulp and the individual packaging sheet 11. It can be composed only of a liquid-permeable top sheet to be wrapped or a surface covering sheet such as a tissue. Such simplification of the structure of the absorbent body 12 not only simplifies the design and cost reduction of the absorbent product P, but also provides a great advantage with respect to the ease of disposal.
[0039]
In order to make the absorbent product P compact and to be able to treat urine hygienically, at least one end of the absorbent body 12 is smoothly and stably accommodated in the trap portion 13, and is liquid. It is desirable that it is extremely thin and excellent in shape stability before and after absorption so that the shape can be stably maintained even after being absorbed and swollen. From such a point of view, the absorbent body 12 used in the present invention has a significantly higher SAP ratio and is more stable than the mixing ratio of SAP to pulp as found in general disposable diapers and sanitary napkins. A sheet-like absorbent body that can maintain the above-described shape, such as those described in JP-A-11-34200, is preferable.
[0040]
FIG. 4 schematically shows the appearance of such a sheet-like absorbent body 12S. This sheet-like absorbent body 12S applies a line coating technique such as curtain coating to the surface of a non-woven fabric, preferably a non-woven fabric having bulkiness and breathability, and is mutually attached along the longitudinal direction of the base sheet 18. It is formed by applying a strip-shaped superabsorbent layer 19 parallel to the substrate. These high absorption layers 19 contain SAP in a proportion of 60% or more, preferably 80 to 90%. Such a sheet-like absorbent body 12S has a good liquid diffusibility because there are only a portion of the base sheet 18 and a portion where the high absorption layer 19 is formed.
[0041]
In order not to impair the swellability of the sheet-like absorbent body 12S, a surface covering sheet such as a nonwoven fabric, a tissue, or a porous film is not used for the sheet-like absorbent body 12S, and at least one end thereof is trapped portion 13 It is desirable to house in. However, it can be folded into an appropriate shape and inserted into the trap portion 13 as required. For example, as shown in FIG. 5, folding portions 20 are formed along both side edges in the width direction of the sheet-like absorbent body 12 </ b> S, and folded portions 21 are formed by folding back one end portion of the sheet-like absorbent body 12 </ b> S. By forming and accommodating the folded portion 21 in the trap portion 13, it is possible to more efficiently absorb the urine discharged to the trap portion 13. Such a shape is suitable, for example, as the absorbent body 12 used for the incontinence pad for men because it becomes easy to hold the male penis between the left and right folding parts 20. The folding part 20 in the present embodiment has a bellows shape having two folding line parts 20f along the longitudinal direction of the sheet-like absorbent body 12S.
[0042]
By adopting a so-called flashable material that can be discarded in a flush toilet as the base sheet 18 and using, for example, an amino acid-based SAP having biodegradability as the SAP, the trap section 13 can be used. It is also possible to take out the used absorbent body 12 and safely discard it in a flush toilet.
[0043]
The bonding tape 15 has a base end integrally bonded to the central portion of the other end of the individual packaging sheet 11, and a pressure-sensitive adhesive (not shown) is attached to the distal end side of the bonding tape 15 that is releasably bonded to the trap sheet 14. Is applied. In the present embodiment, no adhesive is applied to the tip of the bonding tape 15, and this portion is pinched with a finger so that the peeling operation of the bonding tape 15 can be easily performed. The function of the bonding tape 15 is to maintain the individual packaging sheet 11 of the absorbent product P in the folded state shown in FIG. 1 and maintain its sealed hygienic state, and secondly, the individual packaging that is folded back. This is to facilitate the workability when the other end portions of the sheet 11 and the absorbent body 12 are deployed during use. In addition to this, when the absorbent product P is attached to the bottom of a panty or a brief, the bonding tape 15 can have a function for fixing the position of the absorbent product P with respect to the bottom.
[0044]
When the bonding tape 15 has a function for fixing the position of the absorbent product P with respect to the lower exposure, the width of the bonding tape 15 is increased to increase the bonding force, or a plurality of the bonding tapes 15 as shown in FIG. It is effective to provide two (two in the illustrated example) bonding tapes 15 apart from each other.
[0045]
In the joining tape 15 of the present invention, after the absorbent product P is used, the individual packaging sheet 11 is folded back as shown in FIG. 1 to join the joining tape 15 to the trap sheet 14 or the trap portion 13 is wound. It is desirable that a stable re-bonding force can be obtained so that the bonding tape 15 can be bonded to the individual packaging sheet 11 by being wrapped around. From such a viewpoint, it is also possible to use a hook-and-loop fastener such as Velcro (registered trademark) or Velcro (registered trademark) other than the adhesive tape as in the present embodiment as the bonding tape 15. Thereby, the absorbent product P can be sanitized without disturbing the shape of the absorbent body 12. At the time of disposal of the absorbent product P, the absorbent body 12 absorbs urine and is swollen, so that the compact individual packaging state as shown in FIG. 1 is not obtained, but basically no major shape change occurs. In order to cope with the swelling of the absorbent body 12, a multi-folding type as provided in the pants-type diaper is used as the bonding tape 15, so that the bonding tape 15 can be securely attached to the individual packaging sheet 11 or the trap sheet. 14 can be rejoined.
[0046]
When the depth of the trap portion 13 is shallow with respect to the length of the absorbent body 12, the individual packaging sheet 11 and the absorbent body 12 are arranged so that the position of the absorbent body 12 does not shift with respect to the individual packaging sheet 11. In between, the position shift prevention member 22 is interposed. In this embodiment, a hot melt adhesive is used as the misregistration prevention member 22, but there is no need to permanently fix the absorbent body 12 to the individual packaging sheet 11, such as an adhesive or a hook-and-loop fastener. It is also possible to remove from the individual packaging sheet 11 using Alternatively, it is possible to obtain an effect simply by using a non-slip agent or the like as the misregistration prevention member 22 to prevent misregistration. The position, shape, number, and the like of the misalignment prevention member 22 can be arbitrarily selected.
[0047]
In order to bend the absorbent product P along the curve of the wearer's body, an elastic member is joined to both side edges in the width direction of the individual packaging sheet 11 in a stretched state, for example, by about 20%, and the contracting force of the elastic member It is also effective to deform the absorbent product P. FIG. 7 shows a state in which another embodiment of such an absorbent product P is developed, and the absorbent body 12 is omitted for the sake of convenience. The elastic members 23 are arranged along the width direction both side edges of the individual packaging sheet 11 over almost the entire area in the longitudinal direction, but as shown in FIG. 8 showing a developed state of still another embodiment. In addition, the elastic member 23 may be provided in an extended state only on the other end side of the individual packaging sheet 11 on which the trap sheet 14 is not stacked.
[0048]
In a state in which no external force is acting on the absorbent product P, the elastic member 23 acts to shrink the widthwise side edges of the individual packaging sheet 11 with respect to other parts along the longitudinal direction. For this reason, in a wearing state, it can deform | transform so that the both-sides edge part of the width direction of the absorber product P may contact | adhere to a body, and can prevent the leakage of urine from the width direction side edge.
[0049]
The absorbent product P according to the present invention has the above-described embodiment as a basic configuration, and a desired usage pattern can be obtained by adding or changing functions depending on the application. Hereinafter, the absorbent product P according to the present invention will be described in order for each limited application. However, the same reference numerals are used for elements having the same functions as those in the previous embodiment, and descriptions of overlapping parts are omitted. .
[0050]

In any of the embodiments, an opening 17 is formed in the trap portion 13 so that the absorbent body 12 can be taken in and out, but the outer peripheral edge portion of the trap sheet 14 is joined to the individual packaging sheet 11. Thus, it is possible to prevent the absorber 12 from being taken out. FIG. 10 shows an example in which the used absorbent product P is rolled and discarded so that the trap sheet 14 is on the inside, but it is naturally possible to dispose it in a folded state as in the previous embodiment. It is.
[0051]
In the embodiment shown in FIG. 9, the upper half of the trap sheet 14 is made of a mesh sheet that allows free entry and exit of the liquid, and the lower half is made liquid impermeable so that the urine that cannot be completely absorbed by the absorber 12. Is temporarily guided here to make it possible to process a large amount of urine.
[0052]
In the embodiment shown in FIG. 11, a guide member 24 that opposes the female urethral opening and guides urine to the absorber 12 in a diffused state is joined to the central portion of the liquid-permeable trap sheet 14 in a protruding state. It is. The guide member 24 having a structure such as a sanitary tampon or a foamed resin has a function of quickly sucking out the discharged urine and guiding it to the absorbent body 12 through the trap sheet 14 to prevent leakage. it can. Also in this embodiment, one end side (the hatched area in the figure) of the trap sheet 14 is kept impermeable to liquid so that urine can be temporarily stored therein.
